Here is how we get the answer....
First, replace f(x) with y . ...
Replace every x with a y and replace every y with an x .
Solve the equation from Step 2 for y . ...
Replace y with f−1(x) f − 1 ( x ) . ...
Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.

Answer:

Step-by-step explanation:
Given equation:

Expand the left side:

Let all terms on the left side have the same denominator of 7:

Join the terms on the left side:


Let all the terms on the right side have the same denominator of 3:

Join the terms on the right side:


Cross multiply:

Expand:

Add 12x to both sides:

Add 252 to both sides:

Divide both sides by 40:
